In summer with temperatures soaring during the day, most of our energy gets lost simply due to dehydration. Not only does our body need ample water, but it also needs salt and sugar. So, in order to beat the heat we propose an “Automatic Lemon Juice Vending Machine”. This is a very useful system, where the machine pumps in lemon juice, sugar syrup and water all into one single container to make “lemonade”.

The system is based on Atmega family microcontroller. The controller controls the pumps and stirrer motor. The unique feature about this system is that, the user gets to set the percentages of lemon juice, sugar syrup and water according to his own needs; so as to create a perfect glass of “lemonade”. Which means that, anyone can make “lemonade” according their own preferences. So now you can make your own perfect lemonade in a few simple steps. First set the percentage for lemon juice (say x), then set the percentage for sugar syrup (say y) and the rest (100 – (x + y)) will be water. So, the machine will first pump ‘x%’ of lemon juice, then ‘y%’ of sugar syrup and finally the remaining water. After the contents have been pumped into the container, the stirrer starts mixing the contents and finally, you have “lemonade”. The best part about this system is that, the end product is completely natural and nothing artificial. This system can be installed anywhere, for example: a private office, a school, a canteen or at one’s house. This is the most suitable system to fend off extreme temperatures because, it helps you hydrate plus it provides the body those vital salts and sugars. So goodbye to “dehydration” and “low energy”.
